Sorry for the late reply, been a busy weekend of learning unreal for gmtk ^^'

Wasn't too tricky, you guys are storing the save-game progress as plain text and there's a whole bunch of little data snippets in the maps which can be plugged into # Unlockables. I actually only wanted to see if I could see the perk screens (which you can! they're so cool!) - it doesn't affect the pre-built levels obviously but it *does* allow you to say WitchCopPerkPoints = 9 so maaybe take a look at that...

Oh also I recorded a vid of me playing through the maps, too, but I kinda decided against posting it in case you didn't want this stuff too public?

Hah, interesting! We didn't think you could unlock those wizards in the campaign - how did you do it?
